PK Study of IV and Oral Amisulpride in Subjects With Severe Renal Impairment

• Status: Recruiting
• Trial end date: 2021-09-01
• Target enrollment: 0
• Participant gender: All

Summary

The aim of the study is to understand how Amisulpride is taken up and distributed around the body and how quickly it is eliminated, when given by mouth and into a vein in adults with severe kidney disease. In addition it is important to understand how well tolerated Amisulpride is in this patient population. Healthy adults will be studied to provide a comparison.

Criteria

Inclusion Criteria: Healthy Subjects

1. Age 18 to 75 years of age at time of signing ICF.

2. Body mass index (BMI) between 18 and 38 kg/m2.

3. Must be willing and able to communicate and participate in the whole study.

4. Must provide written informed consent.

5. Must agree to use an adequate method of contraception

6. Healthy as defined by:

• The absence of clinically significant illness and surgery within 4 weeks prior to dosing. Subjects vomiting within 24 hours pre-dose will be carefully evaluated for upcoming illness/disease. Inclusion pre-dosing is at the discretion of the Principal Investigator;

• The absence of clinically significant history of neurological, endocrine, cardiovascular, pulmonary, hematological, immunologic, psychiatric, gastrointestinal, renal, hepatic (including cholecystectomy), and metabolic disease;

• The absence of clinically significant history of lactic acidosis and severe hepatomegaly with steatosis;

• The absence of history of suicidal tendency, disposition to seizures, state of confusion, or clinically relevant psychiatric diseases.

7. Normal renal function, i.e., eGFR or creatinine clearance ≥ 90 mL/min/1.73 m2 as calculated using the MDRD4 or Cockcroft-Gault equation; at the Principal Investigator's discretion, 24 hour creatinine clearance may be conducted to determine renal function.

8. Matched to subjects with severe renal impairment for gender, age (± 10 years), and BMI (± 15%) to the extent possible.

Inclusion Criteria: Renal Impaired Subjects

1. Age 18 to 75 years of age at time of signing ICF.

2. Body mass index (BMI) between 18 and 38 kg/m2.

3. Must be willing and able to communicate and participate in the whole study.

4. Must provide written informed consent.

5. Must agree to use an adequate method of contraception

6. A diagnosis of renal impairment that has been stable, without significant change in overall disease status in the 3 months prior to screening as determined by the Principal Investigator, with no requirement for dialysis, and an eGFR at screening < 30 mL/min/1.73 m2 calculated using the MDRD4 equation.

19. Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results at screening.

20. Donation of plasma within 7 days prior to dosing. Donation or loss of blood (excluding volume drawn at screening or menses) of 50 mL to 499 mL of blood within 30 days, or more than 499 mL within 56 days prior to the dosing.

21. Subjects who are taking, or have taken, any prescribed or over-the-counter drug (other than 2,000 mg per day acetaminophen) or herbal remedies in the 14 days before IMP administration
